Hi! I'm not clear about the difference between (XCM,YCM), and (XCCM,YCCM). ¿It is the first pair the Center of mass of the floor, and the other one the center of mass of the cumulative structura actuating in a spefic story floor?

@engrgep 4 жыл бұрын

M hussein with regards to your CM and CR i observed that it is from your gridlines. Meaning ex and ey coordinates is base on the Grid from 0,0 as your ref pt. Does it mean that whatever shape of the building just put the max gridline length for X and Y??? Please correct me if im wrong.

Please help me, why my design in Mass X, Mass Y, and Mass Moment of Inersia the value is 0 ?

@civilmdc 10 ай бұрын

Because I think you didn't define "Mass source"

@IKetutKerthaAdhi 4 ай бұрын

@@civilmdc I'm experiencing the same problem. I've already defined the 'mass source,' but the values in Mass X, Mass Y, and Mass Moment of Inertia are still 0. The values appear in the summary mass of the floor, but they do not appear in the summary mass of the diaphragm.
